No. 31 Myriad Supply

For the work force at Myriad, a company that designs, sells and manages computer networks, it’s all about speed. The nine-year-old company in the Flatiron district began as a bedroom-based eBay operation. It has grown fast, and its young employees keep pace, zipping around its hip loft digs on Razor scooters.

Myriad is also a place where employees rapidly shift gears, said founder Andrew Fisher. Being a quick-change artist helps, too. In the office, the informal dress code includes T-shirts and running shorts, but a client meeting means a dash into the company shower, followed by serious business attire. —Gale Scott
